- Leaking glazing joints on a rooflight
How we handle glazing silicone in Lewes
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you have rooflight joints letting water in and water running down inside the glass, we can put it right, on glass-to-frame joints, glass balustrade bases and shower screens alike.
Plenty of homes in a town like Lewes have had conservatories, patio doors or new windows added over the years. Each one adds more joints to look after, and those joints age at different rates. Sills, frame heads and glazing joints are where leaks generally start.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we’re called out for in Lewes
New silicone over old silicone won’t bond. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Look out for these signs:
- Glass-to-glass joints that have split
- Silicone pulling away from the glass
- Leaking glazing joints on a rooflight
- Black or yellowed silicone on glass joints
For site and facilities teams at buildings such as Lewes Old Grammar School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- How the joint is cleaned and prepared
- Whether you can choose the colour
- What product goes in the joint
- How long to leave it before use
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Failed flashing around a conservatory
- A roof that has moved or dropped
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Common questions in Lewes
Can you do glazing silicone in Lewes?
Yes, Lewes is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.
Do you work for landlords with property near Lewes station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can a conservatory leak be sealed?
That depends where the water is getting in. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
Do you fit new glass or sealed units?
That’s not something we do. A misted unit has failed inside and needs replacing by a glazier.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Is balustrade sealant something you do?
We can, if the base joint is sealed. Photos help us see what’s there.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Why not top up the existing silicone?
It does not last. The new bead can’t grip the old one so we take it all out and start clean.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most jobs. A visit in Lewes needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

Rooflights
Water around a rooflight isn’t always the sealant. We find the cause first.
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.
Lewes homes and the weather
With historic houses such as Anne of Cleves House (about 0.6 miles south) nearby, there’s older building stock in the area around Lewes as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Lewes station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to Church of St John sub Castro include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
